Now to install this harness. The main bundle of the harness runs form the radio to the four headset jacks.  There are also leads from the harness that go to the avionics distribution buss, the dimmer circuit, the audio output of the Enigma, the intercom switch (the last switch to be wired)and to ground.

I connected the headset jacks first and then routed the cable back to the panel.  Once that was done, I then connected all of those other leads to the various locations.  Another complication however was that two pairs of wires attach to the headset mic jacks to enable push to talk buttons in the stick.  Those wires were also connected when I wired up the harness to the jacks.

The last picture is of the completed panel. The radio display is on and the frequency displayed in the radio was sent to it by the Enigma.  If you enlarge the picture you can see that the radio frequency is the fourth one in the list. I just pushed the four key on the Enigma and the frequency popped up on the radio.  Very nice.
